PLAQUE.

SPECIFICATION forming part of Letters Patent No. 598,080, dated February1, 1898. Application filed J'uly 12, 1897. Serial No. 644,262. (Nomodel.)

To all whont it may concern:

Be it known that I, RILEY R. FISH, a citizen of the United States, and aresident of La Grange, in the county of La Grange, State of Indiana,have invented certain new and use ful Improvements in Plaques, of whichthe following is a specification.

This invention relates to a plaque, and has for its object to secure aphotographic print or picture to a plaque wherein the print or pictureshall be hermetically sealed from the action of the atmosphere.

The invention therefore consists in forming the plaque with a depressionhaving inclined sides and securing therein by cement a glass pane whichcarries upon its reverse side the print or picture, the print or picturebeing doubly sealed by a marginal application of enamel devoidof oil andby the cement which secures the glass in the recess of the plaque.

The invention further consists in the parts as hereinafter shown,described; and claimed.

In the drawings, Figure 1 is a plan view of a plaque constructed andarranged in accordance with my invention. Fig. 2 is a sectionalelevation of the same, taken at a point indicated by the line X X,Fig. 1. Fig. 3 is an enlarged sectional view of a portion of the plaque.

A designates the plaque, which is formed with a depression B within itsupper surface, the side wall bof the depression being inclined outwardlytoward the top of the plaque. Extending circumferentially from the bodyof the plaque is the rim 0, preferably formed of filigree-work, in whichmay be threaded a ribbon c, tied with a suitable bow 0', whereby the rimpresents an ornamental appearance. Depending from the body of the plaqueis an annular ridge a, which forms a base for the Seated in thedepression B is a glass or other transparent pane D, having secured uponits lower side a photographic print d, preferably through the medium ofan interposed layer of gelatin, the print being of a diameter less thanthe diameter of the glass pane, and securedto the pane in the space thusformed is a layer E of enamel, which serves the purpose of an ornamentalmat for the print and also to hermetically seal the upper side of theprint from the action of the atmosphere. The enamel used is preferablybicycle-enamel, which must be devoid of oil or greasy matter, as I havefound that the enamels containing oils or other greasy substances affectthe print by discoloration. The pane thus prepared is inserted in thedepression of the plaque, the edge thereof being slightly apart from theinclined Wall of the depression, as shown more fully in Fig. 3, and issecured therein by cement, plaster-of-paris, or other suitable bindingmaterial F, which binds upon the upper edge of the pane and also beneaththe same upon the enamel,whereby the edge of the pane is entirelyenveloped thereby, thus preventing the atmosphere and other extraneousmatter entering the space G between the pane and the plaque. In order toseal the cement or binding to the plaque, if desired, I may form anannular recess 11 in the Wall of the depression, into which the ocmentis forced, as shown in Fig. 3.

It will thus be seen that I have provided a plaque in which aphotographic print or picture may be exhibited, in which the print orpicture is sealed from the action of the atmosphere, and in which thesealing medium (the enamel) will not affect the print or picture, beingdevoid of oil or greasy ingredients.

While I have shown and described the plaque, depression therein, andglass pane as round or circular in form, I wish it understood that theplaque, depression, and pane may be made of any contour withoutdeparting from the spirit of my invention.

What I claim as my invention is- 1. A plaque having a depression in sidethereof, a transparent pane secured in the depression, a print securedthereto through the medium of an interposed adhesive film of gelatin,the print being of smaller area than the area of the transparent pane, alayer of enamel secured around the pane and slightly overlapping thesame, the outer edge of the enamel being inclined inwardly from the edgeof the pane, and a marginal layer of binding material, such as cement,embracing the pane and the enamel, above and below the samerespectively, substantially as described.

2. A plaque having a depression in the upper side thereof, the sidewalls of the depression being inclined, a transparent pane having aphotographic print or picture secured thereon arranged in the depressionand secured therein by a marginal application of binding material suchas cement, plaster-ofparis, &e., embracing the pane above and below theedge of the same, substantially as described.

3. A plaque having a depression in the upper side thereof, a transparentpane having a photographic print or picture secured thereon and sealedby a marginal layer of enamel, an annular groove in the side wall of thedepression in the plaque, the pane being secured in the depression by abinding material such as cement or plaster-of-paris embracing the paneabove and below the edges of the same and extending into the annulargroove in the side Wall of the depression, substantially as described.

In testimony that I claim the foregoing as my invention I have signed myname in the presence of two subscribing Witnesses.
